Railroad Crossing Cradle with Reinforcement Unit Fasteners with Reinforcement Units {RAILROAD CROSSING CRADDLE WITH REINFORCEMENT UNIT}

The present invention relates to a cradle to which the fastening device of the railroad crossing is fastened, and the movable nose block is moved left and right between the wing rails to reduce the breakage or deformation of the wing rail and to facilitate the fastening of the fastening device. It's about the cradle of a railroad crossing.

In general, two rails are laid parallel to each other, so that the rails on which the train runs are driven by the rails on both sides of the train.

Depending on various needs, it is also possible to equip facilities that separate one track in two or more directions, and two tracks may intersect on the same plane.

At this time, a facility that separates one line in two directions is called a turnout, and crossing two lines in the same plane is called crossing.

Crossing allows the tracks to be crossed in a variety of ways, such as diamond crossing where two tracks cross at right angles or large angles, manganese steel crossing formed from manganese steel, and some It is implemented in various forms, such as movable crossing, which is designed to move the rails.

In the case of movable crossing, a movable nose block is provided between the pair of wing rails to move left and right, and a method of guiding the route of a train is widely practiced.

At this time, the point of the cradle, where the tip of the movable nose block is located, frequently deforms the wing rail by repeatedly impacting the movable nose block on both wing rails.

In addition, the point portion is coupled with a fixing device for providing a fixing force to the movable nose block.However, when the fixing device is directly connected to the wing rail, the fastening force of the fixing device is lost due to repeated shocks, resulting in separation or damage. Also happened frequently.

Therefore, a method for solving these problems is required.

The present invention is to provide a cradle of a railroad crossing that has been made to solve the problems of the prior art described above, so that the cradle disposed in the crossing part of the railroad can be more durable and firmly maintained through a reinforcement unit. .

In addition, by providing a separate fastener that can be coupled to the fixing device for fixing the movable nose block to increase the binding force of the fixing device, and to provide a cradle of the railroad crossing with increased resistance to impact.
